The wait is over! CCS tuning can now unlock the true potential of your 3.0L LM2 Duramax. Unlike most tune files on the market, CCS offers true custom tuning for your 3.0L. You just have to let us know what your upgrades and preferences are, and then we will have the tunes written to accommodate any modifications your truck may have. 

By custom tuning a truck, you are given the ability to modify countless parameters to the engine and transmission operation that OEMs had to produce the stock tunes you started with. The number one reason customers choose to tune their trucks is fuel economy. Just by changing the rate of the burn inside the combustion chamber and removing EGR gases (if applicable) from the burn we can extract more energy out of the fuel that was otherwise possible. By extracting more energy out of the fuel we get increased fuel mileage as less fuel is required and an increase of power.
